 When there is no function body, and only a return value, arrow function syntax allows you to omit the keyword <code>return</code> as well as the brackets surrounding the code. This helps simplify smaller functions into one-line statements:
 
 ```js
-const myFunc = () => "value"
+const myFunc = () => "value";
 ```
 
 This code will still return <code>value</code> by default.
